KEYBOARD FOR COMPOSING-MACHINES.

Patented aug. ii, rara. 817,185.

To all 't0/mm 'it may concern Be it known that I, CHARLES E. BENHAM,

a citizen of the United States, residing at Schenectady, county ofSchenectady, State of New York, have invented certain new and usefulImprovements in Keyboards for Comprising-Machines, of which thefollowing is a specification. v

The present invention relates to key boards of so-called composingmachines and in particular to key boards of machines o t the Lanstonmonotype system although it 1s not necessarily limited thereto.4 Ishall, however, describe my invention with reference to such machinesbecause it is particularly applicable thereto..

The ordinary key board in its operation requires that the operator shalldepress and release a key each time its corresponding character is to bereproduced. In my Patent No. 1,099,734, issued June 9, 1914, I havedescribed and claimed an improved key board arrangement whereby anydesired character can be reproduced indefinitely so long as the key isheld in its depressed position by the operator. When the key is releasedthe automatic reproduction of the character' ceases and the operatorproceeds in the usual manner. Suchen arrangement on account of its highspeed of operation requires close attention and considerable skill onthe part of thev operator to release the repeating key at the propertime, especially for tabular work Where the items are to be printed invertical columns with considerable space between them.

The present invention is an improvement over the apparatus disclosed insaid patent.

Briefly the principal feature of my invention resides in the addition ofan arrangement whereby the action of the repeating key is automaticallyinterrupted at the proper time whether it be at the end of the line orat some intermediate point. Two embodiments of thisvidea areillustrated. In one embodiment the operator holds the key depresseduntil a predetermined number of characters or punching operations havebeen made when a device controlled by the movement of some part of themechanism, as the em rack for example, stops further repetition, theoperator then releases the repeating key and proceeds in the normalmanner. This action may take place one or more times for each line ofthe final printed page. In the other embodiment the operator depressesthe repeating key which is imy med1atelylocked in that position bysuitable means and remains so until the device controlled by the em rackor equivalentdevice releases it. From the view point of the op-'bodiments resides in the fact, that in one case he or she must depressand hold the 'rel peating key until the necessary punching operationshave been made when the machine stops, while in the other case it isonly f necessary to depress the key and remove the ringer, after whichthe operations are re# .peated without his or her assistance, until theproper number of operations have been l made when the machine stops andthe kev is returned toits normal position.- u

Uther novel features of my invention will ,be pointed out hereinafter.lV f In the accompanying drawings which are gillustrative of board fittedwith my automatic stop; Figs. 2, 3 and 4 are detail views of theactuating and stopping mecha- Inism; Fig. 5 is a plan view of a deviceto fasten the flexible cord of repeater key Amechanism to the roc -shaftrods; Fig. 6 is ,a sectional view of the valve controlling the lribbonfeeding mechanism; Fig. 7 is a detail View in front elevation of the emrack and stop mechanism; Fig. 8 is a plan view of the key banks; Fig. 9is a sectional `view of the :em rack and stop bar; Fig. 10 is a detailplan Vviewof the means for temporarily locking the repeater key in itsdepressed position, and Fig. 11 is a perspective view of the stop bararranged to coperate with the locking means of Fig. 10.

In'order that my invention may be understood and its relation topreviously existing constructions appreciated, it is necessary to brieydescribe the latter; 11 indicates one of the ordinary keys which, when4depressed by the operator, moves a bar having projections on the underside which in turn moves' the rods 12 mounted on the roc-k shafts 13.Each of these rods when pushed opens a valve 14 to admit compressed airto the cylinder of the motor 15. The piston in the Cylinder movesupwardly carrying with it the lever 16, bar 17 and punch 18, the

latter making holes in the paper ribbon 19.

y'.llie punches generally operate in pairs my invention,y Figure 1 is aperspective view of apart of a Lanston key repeating key and erator, thedifference between the two emret lia

through the action of the rods, and the air pressure closes the valveswhen the key is released. In some cases, as for example with the quadkey, it is common practice to omit the punch from one or more of thebars 17, because certain characteristics of the casting machine in whichthe ribbon is subsequently used, and in particular as regards the meansrender it unnecessary to perforate the paper for this character. Eachbar and lever 1G, however, move up and down for each operation of itsassociated key and the ribbon 19 is advanced step-by-step betweenoperations as in other cases, and hence the operation, except for thepunch perforating the ribbon, is the same in all cases. The two motorsand punch bars shown are typical illustrations of these devices of whicha large number is provided for each machine.

To withdraw the punches and return them to their depressed positions andalso to control the `action of the ribbon feeding means, mechanismincludingr a tension arm 20 is provided that is actuated by a fluidmotor 21 comprising a piston and cylinder. This motor always tends tohold the punches and rods depressed but is overpowered by the motors 15when the latter are active. Connected to the tension arm by a link is alever 22 that assists in the opera-tion of the so-called unit-rackslide.

23 indicates a leverthat is connected to the usual stop mechanism forthe unit-rack slide.

Thel paper ribbon is fed between two perforated die plates 24 by toothedwheels 25. 'The shaft for these wheels is provided with a ratchet wheel26, and the latter is advanced step-by-step by the pawl 27. The pawl isactuated by a rod 28 whose lower end is connected to the vibrating lever29, the latter being tilted first one way and then the other by thepistons 30 and 31. Vhen the machine is at rest the left hand end of thelever is elevated and moves down and up for each punch stroke. Thepistons are controlled by the two-way slide valve 32 which is actuatedby an arm 33 having a cam slot 34, said arm being actuated by thespindle of the tension arm 20. In the Slot is a roller mounted on thelever 35,l the latter movingr the valve 32 to admit air under one pistonand at the same time exhaust it from the other as shown in Fig. 6. Themechanism so far described is old.

As in my said patent I utilize the mechay nism which withdraws thepunches and retracts the bars and specifically the vibrating lever 29 ofthe paper feeding mechanism to perform the work of actuating the valves14 of motors 15 when the repeater key is depressed, but I do it in adifferent manner and attain new and advantageous results. u

40 indicates a liexible connector which can for movin'T the matrix casebest be made of metal cord or chain. It is connected at on-e end to apair of the valvev rods 12 as in my prior patent butv in a diiierentmanner. The rods 12 are connected to the rock-shafts by vertical pins41. Between a pair of pins I slip a strip 42, Fig. 5, of rather thinmetal having notched ends partially embracingr the pins. These stripshave holes 43 to receive the ends of the connectors. One end of eachconnector is first attached to the strip, then the assembler flexes saidstrip with his fingers and slips it between the pins. When released thenotched ends ofthe strip hold the same in place. This greatlyfacilitates the securing of the connectors and rods and also materiallyreduces the labor of adjusting the connector to obtain the exact lengthdesired. In connection with this, as well as other devices toV bedescribed later, it must be Vremembered that one of the very greatfeatures of my invention is that the apparatus can be applied toexisting machines without rebuilding them. The connectorV passes aroundpulley 44 and up over the pulley 45, said pulleys being mounted on theyframe of the machine. In my patent aforesaid the Aother end of theflexible connector 1s connected directly to the vibrating lever 29.

This former arrangement is entirely satisfactory in so far as the workperformed by it is concerned, but it is rather objectionable in somecases from the view-point of wear and tear to have the connectorcontinually subjected to motion. I avoid this by the additionvof a lever46 which is normally stationary and whose fulcrum is, or may be, thesame as that of the lever 29. By using the same fulcrum 47, Figs. 3 and4, for both levers 29 and 46, extra parts and unnecessary work areavoided. The lever 46 may either be flexible in a. plane perpendicularto its length or it can be loosely mounted on its fulcrum to permit itsfree end to be moved away from the lever 29 to disengage the parts, aswill appear later. Carried 'by the auxiliary lever 46 is a pin 48 thatVpro- Y jects into the vertical plane of vibration of the lever 29, butnormally stands'j ust below the region of said vibration and is,therefore, not affected. A spring 49 tends to hold the auxiliary leverdown thereby keeping the flexible connector 40 sufficientlyv taut toprevent idle movement as well as quad out a lineV 'inmates ing parts.lVhen pressure is first applied to the repeating key, the auxiliarylever is held down because the right hand end ofthe main lever 29 restson its pin 48. The upward movement of the punches turns the tension arm20 on its axis together with the arm 83, which shifts the valve 32 tothe left, the latter admitting air under piston 3l by pipe 3l andpermitting it to escape from under piston`30 by pipe 30a. Then the righthand endof lever 29 rises it releases the pin 48 thereby releasing thetension on the connector 40 and valves 14 cut ofl the supply and releasethe air from under pistons 15 and the latter return to normal position.This movement is accompanied by a shifting of the-valve 32 wit-h theresult that the left hand end of the main lever 29 rises and its righthand strikes the pin 48 which restores the tension to the connector 40and the action is repeated until some further act stops it. Owing to thefact that one or more of the motors act in response to a movement of therepeating key, the feeding mechanism will advance the ribbon 19 betweeneach two similar movements, and hence it makes no difference if a punchhas been omitted from a unch bar, providing, of course, as heretofbreexplained in connection with the matrix case of the casting machine, apunch is unnecessary to the successful operation. V'Vhether a punch isused or not the record is made. In the one case the ribbon is perforatedand in the other case not.

I will next describe an arrangement whereby the automatic action of therepeating key can be arrested at any predetermined )oint or points,particularly with the idea o facilitating the work where parallelcolumns in the printed age are required.

The machine is provi( ed with an ein rack extending across the front andcarrying the usual pointer 5G traveling over the fixed scale plate 57.Just below the rack I mount a bar 58 on pivots 59, the latter can bemade of screws and threaded into the frame of the machine, there beingample space for the purpose. This bar is held in the raised positicn bythe spring 58 andhas one or more adjustable stops (30, each having a topwith a right and a left hand beveled face. Carried b v the ein rack is afinger 6l which, when it strikes a stop, depresses the bar and raisesthe arm 62 forming a side extension. This arm when elevated, assumingthe repeating key to be held depressed by the operator, moves the righthand end of the auxiliary lever 46 sidewise by an amount suicient topull the pin 48 out of the region of vibration of the main lever 29, thefinal I result being to release the tension on the connector 40 ascompletely7 asl though the repeating key had been released and themachine stops. The operator is then free to Work the machine in thenormal manner or the stops.

The next key influence of the main lever 29 the are free to moveupwardly at the rear en Subsequently they are returned to normalposition by spring 49. The rear end of the arm 62 is made to form abeveled faced cam so as to assist in moving the rear end of the leverand its pin 48 out of the path of lever 29. A screw 63 enables thenecessary fine adjustment to be made. I have described the adjustingscrew as being mounted on the auxiliary lever, but it can be mounted onthe arm 62.

l Each stop on the front bar 58 is adjustable sidewise and alsovertically and is held in place by a screw (S4. ln order to insure theproper setting of these stops and hence the accurate stopping of themachine, they may be provided with pointers 66 that roject in front ofthe scale plate 57 for the purpose ofcoinparison. By beveling the upperfaces of the stops as shown, the em rack .and finger 61 can be moved ineither direction by the normal mechanism. In other words, aside fromserving as a stopping means or discoiinector for the repeater key, thebar and its stop have no effect. During the usual key-by-key oper-ationthe finger 6l will ride over the stops first depressing tlie bar 58 andkthen releasing it, the auxiliary lever arrangement permitting this totake place.

In Fig. 7 is shown in elevation the relation of certain parts whenmounted in place on the machine. 55 indicates the ein rack which ismounted to slide in the slotted member (37, Fig. 9, said rack beingdriven by the pinion 68 on the shaft 69 of the unit wheel 70. 55indicates a roller for holding the em rack down so that it will not beforced out of place when the finger 6l strikes a stop (50 on the bar 58.The pawl 7l serves to hold the wheel until certain machine operationshave been completed. 72 indicates the so-called driving cylinder and irotates the shaft 69 through the usual means that need not be described.73 is the stop for the em rack 55. Below the rack is the pivotallysupported releasing bar 58 for the repeating key 50. Above the bar isthe scale plate 57 which is common to the ein rack pointer 56 and to thepointers 6G on As constructed the em rack pointer 56 and the finger (ilare made of one piece, said parts extending through small holes in theem rack and being united on .the back by (36, Fig. 9, after the fashionof a hair pin. This has the advantage that the pointer 5G prevents thefinger Gl from turning when it strikes a stop. The arrange- 'ment issimple .in the extreme and also avoids additional clamping means whichwould cost money to -make and would be more or less in the way.

In Fig. 8 is shown an arrangement Whereby tworepeating keys 50 and 74,representing for examplea quad and a. leader, are located in the rightand left hand key banks. Key 50 acts through the push rod 5l on lever52, and key 74 through push rod 75 on the bell crank lever 76, the`latter being connected by a link 77 to the lever 7 8. The levers areconnected'by flexible connectors 53 and 79 to the main connector 40,Fig. 1. The levers are held in tension by the springs 80. Each lever hasa stop 78a to limit its movement. It will thus beseen. that eitherrepeating key may be used to control the auxiliary lever 46, Fig. 1. Itis to be understood, of course, that where the keys represent differentcharacters, as they nearly al- Ways. would, two connectors 40 areprovided Which extend to differ-ent pairs of rods 12.

As described thus far it is necessary for the operator to hold therepeating key down so long as it is desired to repeat the samecharacter. That is to say, until the finger 61 automatically causes therelease of auxilia'ry lever 46.l I will now describe a means whereby theact of depressing a lrepeating key in addition to starting the mechanisminto automatic action Vwill lock said key in it-s depressed positionuntil released by the action of the iinger 61, stop 60 and bar 58. Thisis a feature ofA Treat importance when combined' with a sultablestopping means for it saves Work andv mental strain on the operator. Italso gives the operator time in which to perform other Work or move hishand preparatory to striking a normal key. As an illustration of thisfeature of my invention I have shown in Figs. 10 and l1 the bar 58provided with a suitably guided arm 85 which extends in front of thelevers 52 andl 78. This arm is provided with tvvo notches 86 and 87 theformer' occupying a position in front of a projection 88, Fig. 10, onthe lever 52 and the latter a position in front of projection 89v onlever 7 8. The portions of the arm adjacent the notches have beveledfaces 90 and 91 over which`- the projections 88 and 89 ride. Theselevers are connected b flexibleconnectors 53 and 79 to the auxi iarylever 46, or they may be connected to the main vibrating lever 29 asdescribed .in my previous patent aforesaid. The levers 52 and 78 overlapto reduce the overall total length. They are held in the position shownby extension springs 98 of suitable strength, which are secured at one-end to fixed supports on the machine frame and at the other ends tothelevers. The

lever 78 has a projection 78a that extends below it and forms a stop.The other lever is also provided with a similar stop.

When the operator depresses key 50 the push rod 5l turns the lever 52against the tension of its spring-until the projection 88 drops into thenotch 86. This action sufiices to put the connector 40 under thenecessary tension to cause the automatic repetition of the unch rodscontrolled by the key as alrea y described. In addition the vWall of thenotch holds the rojection 88 and locks the lever 52 so that t e operatorcan release the key without stopping the automatic action. The punchesWill continueV to 'make holes in the paper ribbon 19, Fig. 1, or therods to move up and down until the finger 61 `on the em rack 55 strikesa stop'GO and depressing the bar 58 moves the arm 85 and its notches adistance sufficient to release the projection 88 and the machine stops.The action is the same for the other repeating key 74 except that theprojection 89 enters the notch 87 and is held unt-il released by a'downward movement of the bar 58. When the tension on the connector isremovedby releasing either the lever 52 or 78 the spring "58, Fig. 2,returns the auxiliary lever to its normal position Where the movementsof the main lever 29 do not affect it.

The flexible connectors can be made of any suitable material but afterconsiderable experiment-ing I have found the small chains used onpull-sockets for incandescent lamps .to be the best, as they are notonly very fiexible but are exceedingly strong for their size and do notstretch.

The combination `of my repeating key mechanism with stop mechanismactuated by some movable part of the machine, asthe em rack for example,is of importance ioo for various kinds of Work but has its greaty est.value for tabular Work Where one, two or more columns are to appear onthe printed page, the remainder being quadded out or filled With dots,dashes, or other characters. It saves the operator both mentally andphysically and insures absolute alinement of the various items in .thecolumns as I have demonstrated 1n practical Work. I prefer to use the emrack as a device to actuate the stop mechanism because it. is in plainvie'W and enables my improvement to be applied to existing machineswithout rebuilding, thereby increasing its field of usefulness, but I donotjwish to be understood as limiting myself thereto. Furthermore, thearrangement permits me to use one scale plate for the em rack pointerand the adjustable stops.

The locking of the repeating key in its depressed position is desirablein all cases because it relieves the operator mentally and physically.It has its greatest utility of course for tabular Work, or Workrequiring continued use of the leader, quad or dash character. Bycombining the stopping and locking mechanism in one structure, as ingroesse Figs. 10 and 1l, I simplify the mechanism as a whole, reduce thenumber of parts and am able to locate it ivhcre it is accessible.

I have described my improved arrangement as depending for its action onthe auxiliary lever i6, and in some instances on the main leverv 29,because either of these arrangements can be applied with the minimumamount of labor and expense. It is evident, however` that luy inventionis not necessarily limited thereto since other vilirating parts of theusual operating mechanism can be employed. This is particularly truewhere the improvement is being incorporated in a new design where oneneed not be bound by the limitations imposed by existing structures andwhere success or failure is not so completely determined by simplicityand the ease with which the improvement can be added. It is also evidentthat while I have described the con.` nector between the valve means orcontroller for the motor and the mechanism movin in synchronism with thefeeding of the rib on f as beinfr flexible. m invention is not to beconstrued as being so limited unless so stated in the claims.

In accordance with the provisions of the patent statutes, I havedescribed the principle of operation of my invention, together with theapparatus which I now consider to represent the best embodiment thereof;but I desire to have it understood that the apparatus shown is onlyillustrative, and
